INHALER.

SPECIFICATION forming part of Letters Patent No. 311,314, dated January 27, 1885.

Application filed October 2l, 18S/1.

T0 all whom, t may concern:

Be it known that I, CORNELIUS BENNETT HARNEss, electrician, a subject of the Queen of Great Britain, residing at London, England, have invented an improved apparatus for facilitating the inhalation of medicated vapor for strengthening, enriching, and extending the range of the human voice, and for the treatment of pulmonary and other affections, for which I have obtained a patent in Great Britain,No. 10,500,bear ing date July 23,1884,) of which the following is a specification.

My invention relates to an improved apparatus for facilitating the inhalation of medicated vapor for strengthening, enriching, and extending the range of the human voice, and for the treatment of pulmonary and other affections. Its chief object is to provide means for enabling the person using the apparatus to regulate or control the supply or admission of air to the same in a very convenient, simple, and efficient manner.

My improved apparatus is illustrated in the accompanying drawing, which shows the same partly in elevation and partly in longitudinal central section. p

a is a tube, which may be of block-tin or other suitable metal or material, and which is provided with a mouth-piece, b, midway between its ends. A ferrule or ring, c, having an internal screw-thread, is soldered or otherwise fixed in each end ofthe tube a.

d d are handles of wood or other suitable material, each provided with an externallyscrew-threaded piece, e, which ts into one of the rings or ferrules c, so that the said handles may be screwed to the tube or unscrewed there from at will.

Through each of the handles d is passed a rod, f, one end of which extends through the piece e and carries a plate or disk, f. This plate or disk is provided ou its inner face with a washer, g, of leather, india-rubber, or other suitable material, so as to form a valve capable of closing the orice or passage c in the piece."

e. A spiral spring, h, is placed upon each of the rods f, so that it bears at one end upon the end of a recess or cavity, d', in the handle, and at the other end upon a cap or push-piecafz, This (No model.) Patented in England July 23, 18S-l, No. 10,500.

spring tends to press the washer g against the end ofthe piece e, and thus close the orifice or passage e, thereby preventing the admission of air to the tube a through the said orifice. The opening of the said valve is effected by pressing upon the cap or push-piece f2, and thereby forcing the rod f inward against the action of the spring h. A small aperture, t', is formed in each ofthe handles d, for the admission of air to the tube a when the said valve is opened. The mouth-piece b has a perforated screw cap, b. This cap is made somewhat larger in diameter than the other part of the said mouthpiece,so that thc latter can be easily retained in the mouth; but the said mouthpiece may, if desired, be made in any other suitable manner.

By providing the ends of the tube a with the ferrules or rings c, I insure the tightness of the joints between the said tube and the handles by forming a wider surface for the said joints than would otherwise exist. I prefer to insert a ring or washer of elastic material between the ends of the tube a and the handles d.

In preparing myimproved apparatus for use one of the handles d is removed from the tube a, and the substance or compound the vapor of which is to be inhaled is placed within the said tube, (which is preferably lled with sponge, cotton-wick, or other absorbent material.) The said handle is then screwed tightly to the end of the tube and the apparatus is ready for use, the said tube being kept airtight by the pressure of the valves upon their seats.

The person desiring to use the apparatus grasps the two handles d and applies his mouth to the mouth-pieceb. Then by pressing one or both of the caps or push-pieces f2 he opens the orice or orifices c for the admission of air to the tube a. He can then conveniently inhale the vapor of the substance contained in the tube, and at the same time regulate or control the supply or admission oi' air to the said tube by pressing more or less upon the said caps or push-pieces.

I do not confine myself to the particular form of construction shown in the drawing, as it is obvious that the same may be somewhat modified. For example, the rods for oper- IOO the mouth-piece b, of the handles d, screwed f into the same and provided With valves and means for operating them to regulate or control the supply or admission 0f air to the said tube, substantially as and for the purpose set forth.

2. The combination, with the tube a, having the mouth-piece b, and provided 'with the ferrules c e, secured in each end of said tube, of the handle d, screwed into said ferrules, and provided with valves and means for operating them, substantially as described.

3. The combination, with the tube a, having the mouth-piece b, of the tubular handles d, screwed into the same, and having apertures fi, the rods f, valves f', caps or push-piecesf, and the springs h, substantially as and for the purposes set forth.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
